Which DNA polymerase is most fidelity-oriented?

DNA polymerase III is considered the most fidelity-oriented of the three polymerases because it facilitates precise DNA replication with fewer mistakes compared to DNA polymerase I and DNA polymerase II. This is because DNA polymerase III possesses a 3' to 5' exonuclease activity, which allows it to remove incorrect nucleotides immediately after they are added.
